Advantages of the Invention

The invention is based on a method for an, in particular at leastsubstantially forgery-safe, assignment of at least one creator to adigital media file, with at least one method step in which the digitalmedia file is recorded by means of a recording device of the recordingapparatus, in particular a front-facing camera of the recordingapparatus, and is provided with metadata, wherein the metadata comprisesat least one creator information, the creator information being realizedas a user identifier and being generated automatically, in particular bythe recording apparatus, preferably by an application software of therecording apparatus, in the recording period of the digital media file,and wherein in the method step at least the user identifier, inparticular at least a user identity, is determined and/or verified by asafety device.

It is proposed that the safety device comprises a camera of therecording device, in particular a rear-facing camera of the recordingapparatus, by means of which the determination and/or verification ofthe user identifier, in particular the user identity, of the user makingthe recording is carried out by the recording device in the recordingperiod of the digital media file. This in particular enablesadvantageous creator identification. It is advantageously possible tomake sure that the user initiating the recording of the digital mediafile is also defined as the creator of the digital media file.Advantageously, moreover an especially simple and user-friendlyautomated user identification of a user creating a digital media file isenabled. It is also advantageously possible to facilitate especiallysimple and user-friendly automated creation of a digital media filecontaining creator information. Advantageously an especially simple, inparticular time- and cost-saving, creator documentation is enabled for adigital media file. Advantageously a high degree of information safetyis attainable.

A “digital media file” is in particular to mean an acoustic and/orvisual digital media file, for example a sound file or preferentially animage file or a video file. Particularly preferentially the digitalmedia file is implemented as a digital photograph. A “recording device”is in particular to mean a recorder, e. g. a sound and/or imagerecorder, preferably a microphone and preferentially a camera, inparticular digital camera. The recording device is in particularintegrated in the recording apparatus, for example as a smartphonecamera or as a camera lens of a digital camera. By “metadata” is inparticular structured data to be understood which contains informationof features of the respective digital media file. Preferably themetadata is integrated in the digital media file and/or inseparablyconnected with the digital media file.

The term “in the recording period” is in particular to mean a temporalproximity of a recording of the digital media file, in particular of anactivation and/or deactivation of the recording, and/or of the recordingperiod the digital media file and/or an exact time of the recording oran exact recording period. The temporal proximity in particular extendsover few seconds (e. g. maximally 10 s, maximally 6 s, maximally 3 s orno more than 1 s) or preferably over few fractions of a second (e. g.maximally 1/10 s, maximally 1/100 s or maximally 1/1000 s).Preferentially the temporal proximity extends over a period that startsat most ten seconds, advantageously at most one second, preferably atmost a tenth of a second and particularly preferably at most a hundredthof a second before the recording and/or before the recording period,and/or ends at most ten seconds, advantageously at most one second,preferentially at most a tenth of a second and particularlypreferentially at most a hundredth of a second after the recordingand/or after the recording period. However, it is also conceivable thatthe recording period extends over a time interval that can be set by auser and/or over a time interval during which the user is reliablyidentifiable by the safety device, for example by a user's voice beingrecognized repeatedly or by the user's face being permanently in a viewfield of a camera of the recording apparatus.

By a “user identifier” is in particular a feature to be understood whichis linked to a user's identity and is preferably configured for anunambiguous identification of the user. The user identifier may beembodied, for example, as a user authentication, in particular a userauthentication based on a Distributed Ledger Technology (DLT), inparticular a user authentication based on a DLT technology having adirected acyclic graphs (DAG) architecture, preferably a DLT technologyhaving a transaction-based directed acyclic graphs (TDAG) architecture,for example as an IOTA™-ID, as a name, as a user code, as a biometriccharacteristic, or something like that. In particular, in the recordingperiod of the digital media file the user identifier is automaticallyadded to the metadata of the recorded digital media file as a creatorinformation, in particular by the recording apparatus, preferably by anapplication software (app) of the recording apparatus. Preferably theuser identifier is stored in the recording apparatus and/or in the appof the recording apparatus. Alternatively, the user identifier may bestored on a server, for example a cloud, which can be queried by therecording apparatus and/or by the app of the recording apparatus, inparticular after determination and/or verification by the safety device.In particular, the safety device is configured to capture and/ordetermine at least one safety feature of a user that is unambiguouslyassignable to the user. In particular, the safety device is configured,in particular in a combination with the app, to check at least onesafety feature of a user that is unambiguously assignable to the user,for example by matching the safety feature with an internal database ofthe app or with an external database that can be queried by the app. Inparticular, the safety device is configured, on the basis of checking atleast one safety feature, to permit an assignment of a recorded digitalmedia file to an identified user, in particular user identifier,preferably by the app of the recording device. “Configured” is inparticular to mean specifically programmed, designed and/or equipped. Byan object being configured for a certain function is in particular to beunderstood that the object fulfills and/or executes said certainfunction in at least one application state and/or operation state.

Furthermore, it is proposed that at least a face recognition and/or afacial-feature recognition is carried out by the safety device for adetermination and/or verification of the user identifier, in particularthe user identity, of the user making the recording. This in particularenables advantageous creator identification. In particular, a highdegree of forgery safety is advantageously attainable. Advantageously,particularly reliable creator identification is enabled. Moreover, thisadvantageously allows especially user-friendly identification of theuser, which is preferably operation-free for the user. In particular,the face recognition and/or the facial-feature recognition are/iseffected on the basis of images recorded by the camera, in particularduring the recording of the digital media file by the recording device.For example, during a recording of an image or video by the front-facingcamera of a smartphone, a face recognition of the creator of the imageor video is carried out in parallel by the rear-facing camera of thesmartphone, wherein the user identity determined by the face recognitionor the user identifier determined by the face recognition is stored inthe metadata of the image or video as a creator information. Inparticular, the user making the recording is the creator of the digitalmedia file. It is in particular conceivable that the face recognitionand/or facial-feature recognition carried out by the safety device isimplemented using the Face-ID® technology of the Apple company(Cupertino, USA). It is in particular conceivable that the safety devicecomprises more than one camera of the recording apparatus, for exampleat least one TrueDepth® camera like the cameras built into theapparatuses of the Apple company (Cupertino, USA), a 3D camera and/or aninfrared camera, in particular in a combination with a point projector,and/or an infrared illuminator, preferably for carrying out a Face-ID®face recognition and/or a Face-ID® facial-feature recognition.

It is also proposed that the recording device is realized as thefront-facing camera of the recording apparatus, wherein a view field ofthe front-facing camera and a view field of the camera, which is inparticular embodied as a rear-facing camera of the recording apparatus,are oriented or can be oriented in at least substantially opposeddirections. In this way in particular advantageous creatoridentification is enabled. Advantageously this allows especiallyuser-friendly identification of the user, which is preferablyoperation-free for the user. “Substantially opposed” is here inparticular to mean an orientation of a direction relative to a referencedirection that is opposed by 180°, the direction having a deviation fromthe reference direction that is opposed by 180° which is in particularsmaller than 8°, advantageously smaller than 5° and especiallyadvantageously smaller than 2°.

If the user identifier is pseudonymized or de-identified, advantageouslya high level of information safety is attainable. It is in particularconceivable that an assignment of the user identifier to a useridentity, i. e. in particular a re-identification or ade-pseudonymization, is carried out by the local app, by a centralserver administrated, for example, by a provider of the app, or by anexternal institution, for example the IOTA™ foundation. In particular,the user identifier, the user identity and/or the assignment of useridentifier and user identity are/is encoded by DLT technology. It isconceivable that the user identifier is safely assigned to a useridentity via a known Know-Your-Customer method, like for example aPost-Ident method or a Video-Ident method. This in particularadvantageously allows augmenting forgery safety.

It is further proposed that the metadata comprises at least one furthercreator information, which is realized as a blockchain timestamp or as aDigital Ledger Technology (DLT) timestamp, in particular a DAGtimestamp, preferably a TDAG timestamp, and which is automaticallygenerated in the recording period of the digital media file, and ispreferably added to the metadata of the recorded digital media file.This in particular enables further improved creator identification.Advantageously, it possible to further increase forgery safety, inparticular using the blockchain technology or the DLT technology, inparticular with the DAG architecture, preferably with the TDAGarchitecture. In particular, the blockchain timestamp or the DLTtimestamp is automatically generated by the app or by the recordingapparatus at the time of the recording of the digital media file and ispreferably added to the metadata of the digital media file. Inparticular, the blockchain timestamp or the DLT timestamp is based on aninternal time of the recording apparatus or on a synchronized timeobtained from the internet at the time of the recording of the mediafile. In particular, the internal time of the recording apparatus issynchronized regularly and/or with an existing internet connectivity ofthe recording apparatus.

Beyond this it is proposed that the metadata comprises at least onefurther creator information, which is implemented as an applicationsoftware identifier, which is automatically generated in the recordingperiod of the digital media file, and which is preferably added to themetadata of the recorded digital media file. This in particular enablesfurther improved creator identification. It is advantageously possibleto further augment forgery safety. In particular, it is conceivable thatthe application software is provided with the, preferablycertificate-based, application software identifier, for example an IOTA™ID, which is preferably added to the metadata of each digital mediafile, in particular during its recording.

In addition, it is proposed that the metadata comprises at least onefurther creator information, which is realized as a hardware identifier,which is automatically generated in the recording period of the digitalmedia file, and which is preferably added to the metadata of therecorded digital media file. This in particular enables further improvedcreator identification. It is advantageously possible to further augmentforgery safety. It is in particular conceivable that the recordingapparatus is provided with the, preferably certificate-based, hardwareidentifier, for example an IOTA™ ID, which is preferably added to themetadata of each digital media file that is recorded using the hardware,i. e. in particular the recording apparatus, in particular during arecording of the digital media file.

It is further proposed that the metadata comprises at least one furthercreator identification, which is realized as a recording locationidentifier, which is automatically generated in the recording period ofthe digital media file, and which is preferably added to the metadata ofthe recorded digital media file. This in particular enables furtherimproved creator identification. It is advantageously possible tofurther augment forgery safety. In particular, the recording locationidentifier comprises geographic coordinates of the recording location,for example GPS coordinates. In particular, the geographic coordinatesare determined in the recording period by the recording apparatus, inparticular by a navigation device of the recording apparatus, and aretransmitted to the app and/or added to the recording locationidentifier. In particular, the recording location identifier mayalternatively or additionally comprise sensor data of anenvironmental-condition sensor, for example a temperature sensor, ahumidity sensor, an air pressure sensor, a brightness sensor, or thelike.

If moreover the creator information, in particular the blockchaintimestamp, the DLT timestamp, the pseudonymized or de-identified useridentifier, the true user identity, the application software identifier,the hardware identifier and/or the recording location identifier,preferably the metadata, is/are registered, encoded and/or secured viablockchain technology or via DLT technology (for example by means of aTDAG architecture like IOTA™), a particularly high degree of forgerysafety is attainable. In particular, the metadata and/or the creatorinformation are/is advantageously inseparably connected with the digitalmedia file. In particular, the creator information is encoded and/orsecured by the app and/or by the recording apparatus via blockchaintechnology or via DLT technology (e. g. IOTA™). By a “DLT technology” isin particular a DLT technology to be understood which has a directedacyclic graphs (DAG) architecture, preferably a transaction-baseddirected acyclic graphs (TDAG) architecture.

If furthermore the digital media file, in particular together with themetadata, is registered, encoded and/or secured via blockchaintechnology or via DLT technology, in particular via a DLT technologyhaving a DAG architecture, preferably via a DLT technology having a TDAGarchitecture, a particularly high level of forgery safety is attainable.Advantageously it can be ensured that unauthorized use of the digitalmedia file is not possible. It is advantageously possible to make surethat the digital media file cannot be opened or distributedindependently from the metadata. Advantageously unauthorized separationof the digital media file and the creator information can be prevented.Advantageously an assignment of the digital media file to a user isobtainable that is traceable without alteration.

Beyond this it is proposed that the safety device, in particularadditionally, comprises a fingerprint scanner, by which in the recordingperiod of the digital media file additionally a fingerprint of the useris captured and/or analyzed for the purpose of a determination and/orverification of the user identifier, in particular of the user identity,of the user making the recording. This advantageously allows furtheraugmenting safety, in particular forgery safety. It is advantageouslypossible to ensure that the user initiating the recording of the digitalmedia file is also defined as the creator of the digital media file.Advantageously, a multi-step safety procedure is facilitated, inparticular in a combination with further methods for a useridentification of the safety device (e. g. a user identification via theaforementioned Face-ID® technology of the Apple company). In particular,the fingerprint scanner is integrated in the recording apparatus. It isfor example conceivable that the fingerprint is captured when a triggerof the recording apparatus that starts the recording of the digitalmedia file is triggered. In particular, it is conceivable that thefingerprint is directly stored in the metafile as a creator information,or that the fingerprint is merely used for an additional localverification of the user identifier and only the determined useridentifier is stored in the metafile.

It is further proposed that the safety device, in particularadditionally, comprises an iris scanner by which in the recording periodof the digital media file additionally a characteristic iris pattern ofthe user is captured and/or analyzed for a determination and/orverification of the user identifier, in particular the user identity, ofthe user making the recording. This advantageously allows furtheraugmenting safety, in particular forgery safety. It is advantageouslypossible to make sure that the user initiating the recording of thedigital media file is also defined as the creator of the digital mediafile. Advantageously, a multi-step safety procedure is facilitated, inparticular in a combination with the further methods for a useridentification of the safety device. In particular, the iris scanner isintegrated in the recording apparatus. It is for example conceivablethat the iris pattern is captured when looking through a viewfinder ofthe recording apparatus, in particular during a recording of the digitalmedia file. In particular, it is conceivable that the iris pattern isstored directly in the metafile as a creator information, or that theiris pattern is merely used for an additional local verification of theuser identifier and only the determined user identifier is stored in themetafile.

If the iris scanner is integrated in the viewfinder of the recordingapparatus, especially simple and/or intuitive iris recognition isadvantageously enabled. Advantageously, a high level ofuser-friendliness is achievable in this way.

It is furthermore proposed that the safety device comprises amicrophone, via which in the recording period of the digital media fileadditionally a voice characteristic of the user is captured and/oranalyzed for the purpose of a determination and/or verification of theuser identifier, in particular the user identity, of the user making therecording. This advantageously allows further augmenting safety, inparticular forgery safety. It is advantageously possible to make surethat the user initiating the recording of the digital media file is alsodefined as the creator of the digital media file. Advantageously, amulti-step safety procedure is facilitated, in particular in acombination with the further methods for a user identification of thesafety device. In particular, the microphone is integrated in therecording apparatus. It is for example conceivable that if a user isrecognized by his/her voice characteristic in pre-definable timeintervals, in particular short repeated time intervals (seconds orminutes), an unlocking of the recording apparatus is maintained for acertain user identifier, and in particular the same user identifier isautomatically assigned to all digital media files recorded during theunlocking, preferably without requiring renewed user identification foreach of successively created digital media files. This advantageouslyallows further increasing user-friendliness.

Moreover, it is proposed that in the method step a digital media filecomprising a pictorial representation of a person, in particularpermitting identification of the person, is recorded, wherein in atleast one authorization step, which in particular temporally follows themethod step, preferably by the recording apparatus, a right-of-userequest is sent to the person depicted in the pictorial representation.This advantageously allows concluding a user agreement between the usermaking the recording and the depicted person in a particularly simpleand/or direct manner (on the spot). It is thus advantageously possibleto dispense with a laborious exploitation of rights, in particular viaan intermediary distribution platform. Advantageously an especiallysimple management of rights is enabled, saving time, costs and/or workinput. In particular, the authorization step comprises electronictransmission of the right-of-use request, preferably as an electronicnotification, from an apparatus, in particular from the recordingapparatus of the user making the recording and/or from a furtherapparatus (e. g. a smartphone or a tablet connected to a recordingapparatus that is embodied as an external camera) which is connected tothe recording apparatus of the user making the recording via aninterface, like for example BLE, USB, etc., to an apparatus, inparticular a display device of the depicted person, like a smartphone.In particular, the right-of-use request comprises a Yes/No queryregarding a grant of the right of use of the digital media file.Alternatively or additionally, the right-of-use request may comprise amonetary offer for a grant of the right of use. Alternatively oradditionally, the right-of-use request may comprise a proposal for arestriction of the right of use (e. g. grant of a right of use that istemporally limited or is restricted to a specific use like a specialadvertising campaign, or something like that). Alternatively oradditionally, the right-of-use request comprises an input option for thereceiver of the right-of-use request for inputting a suggestion of aprice for granting the right of use or for inputting a temporal limit ofthe grant of the right of use. Advantageously, the user identifier, inparticular the user identity, of the user making the recording isalready determined in the method step, such that the person requestingthe right of use and/or the person who is granted the right of use whenthe right-of-use request has been accepted, are/is already identifiedbeyond doubt and/or can be incorporated in the right-of-use agreement.

If in at least one analysis step, which is in particular located betweenthe method step and the authorization step, the digital media filerecorded in the method step is checked for images of persons,advantageously a high level of user comfort is achievable.Advantageously, a generation and/or transmission of the right-of-userequest can be simplified and/or at least partially automated. Inparticular, the recording apparatus executes a computer-based imagerecognition routine, which is configured to recognize at least images ofpersons, preferably identities of persons.

If furthermore, upon recognition of an image of a person in the analysisstep, an order to carry out the authorization step is outputted,advantageously an especially high level of user-friendliness is broughton. Advantageously, for example, in particular on the basis of theresult of the analysis step, an automated query may be made whether aright-of-use request should be generated and/or sent out. For example, aquery by the recording apparatus is conceivable in which the recordingapparatus inquires whether a person in a digital media file who wasrecognized in the analysis step is a publicly known person (meaningpersons of contemporary history or public persons, for examplepoliticians, actors, etc.) or a person who is not known to the public.

It is further proposed that in the authorization step the digital mediafile is transmitted to a display device of the depicted person. In thisway an especially high level of operating comfort is advantageouslyachievable. Moreover, it is advantageously possible to unambiguouslydefine the digital media file concerned by the right-of-use. It is alsoadvantageously possible to facilitate and/or accelerate a decision ofthe depicted person regarding grant or refusal of the right of use. Inparticular, the respective digital media file is transmitted togetherwith the right-of-use request. In particular, transmission of thedigital media file and/or the right-of-use request between the user whomakes the recording and the depicted person is effected wirelesslyand/or by radio transfer. However, alternatively cable-boundtransmission is of course also conceivable.

If advantageously a right of use regarding the digital media file whichcontains the pictorial representation of the person can be temporallylimited by the depicted person within the authorization step, increasedcontrol of the person of his/her right to his/her own image isadvantageously enabled. It is in particular conceivable that theright-of-use request contains a reply option allowing the person toadjust the temporal limitation.

In addition, it is proposed that a right of use regarding the digitalmedia file which contains the pictorial representation of the person,which was granted by the depicted person, is registered and secured viablockchain technology or via DLT technology. This advantageously enablesa manipulation-proof documentation of a granted right of use, which waspreferably granted irrevocably or in a temporally limited manner, in atangle of the DLT technology and/or in a blockchain of the blockchaintechnology. This advantageously allows preventing misuse and/or fraud aswell as increasing legal security. In particular, moreover a time ofgrant of the right of use, a time interval of the right of use, anamount of a usage fee paid, an unambiguous identifier of the digitalmedia file, the user identifier of the user making the recording and/orof an owner of the right of use, an identifier of the depicted personand/or of the person granting the right of use, and/or the digital mediafile concerned by the right of use are/is registered and/or secured bymeans of blockchain technology or DLT technology.

Furthermore, a method is proposed for an, in particular at leastsubstantially forgery-safe and decentralized, distribution of digitalmedia files which metadata are assigned to by the method describedabove, wherein the digital media files and/or at least the metadata ofthe digital media files are registered and/or encoded by the blockchaintechnology and/or by the DLT technology, preferably by the DLTtechnology having the DAG or TDAG architecture, wherein when the digitalmedia file is used, for example when the digital media file is accessedor when the digital media file is transmitted, the user identity or theuser identifier of the creator of the digital media file is read outfrom the metadata of the digital media file, and thus usage conditionsdefined by the identified creator are ascertained, wherein the usage, inparticular access and/or transmission, of the digital media file ispermitted or prevented depending on the defined usage conditions. Inthis way it is possible to obtain advantageous control of transmission,sharing and/or usage of digital media files protected by copyright laws.Advantageously, unauthorized transmission, sharing and/or usage ofdigital media files protected by copyright laws can be prevented.Advantageously, legal distribution and/or licensing and/or legal sale ofrights to digital media files may be rendered possible without anintermediary instance, like for example an image agency, preferablydirectly from a creator to an end user. This advantageously allowsdispensing with computing capacities, costs and/or time delays caused bythe intermediary instance.

By “decentralized distribution” is in particular a distribution to beunderstood which is free of the intermediary instance, like for examplethe image agency, and which is preferably effected directly from acreator and/or owner to a user. It is for example conceivable that thedistribution is effected directly from the creator's recordingapparatus. For this, the user is in particular, via an internetconnection, given access to the recording apparatus, preferably topreviews of digital media files stored on the recording apparatus.Preferably the user may then request one or several digital media file/slocated on the recording apparatus and, after fulfilling the usageconditions, for example after approval of a currency transaction, inparticular a cryptocurrency transaction and/or a micropayment, forexample a bitcoin transaction, Ethereum transaction or an IOTA™transaction, the user is allowed to download the digital media file fromthe recording apparatus. In particular, the user is permitted to filterthe digital media files on the recording apparatus and/or to search thedigital media files on the recording apparatus by means of a searchfunction.

If the usage conditions comprise at least a defined usage fee, inparticular a usage fee defined by the creator of the digital media file,by an owner of the digital media file and/or by a central or decentraldistribution platform, advantageously an especially simple remunerationsystem for creators of digital media files can be created saving time,costs and/or work input. In particular, the usage fee is a payableamount in a Fiat currency, in a cryptocurrency, like for examplebitcoin, Ethereum coin, IOTA, preferably with a micropayment function. Adecentral distribution platform may for example be a platform, operatedby a single creator or by a group of creators, on which the digitalmedia files are offered, for example a website or just a recordingapparatus released for public access or for public search.

Beyond this it is proposed that when the digital media file is used, auser identity or a user identifier of a user is ascertained and thedefined usage fee is automatically requested and/or collected from theuser and/or transferred to the creator, the owner or the distributionplatform. In this way it is advantageously possible to create aremuneration system for creators of digital media files which savescomputing resources, time and/or energy input. Advantageously a highlevel of user-friendliness is achievable. Alternatively, it isconceivable that the usage condition, for example the usage fee, isdefined in advance, which means that it is not requested separately ordoes not have to be requested separately with each usage and/or eachtransmission.

It is further proposed that a transmission of the digital media file viaa social media platform, like for example Facebook™, or via a chatplatform, like for example WhatsApp™, constitutes a usage of the digitalmedia file. This advantageously allows legal sharing of digital mediafiles which are protected by copyright laws. In particular, with eachtransmission or sharing of digital media files, the metafile of thedigital media file is read out by the social media platform or by thechat platform, and it is thus determined whether the usage conditionspermit sharing or transmission, wherein in particular—if applicable—ausage fee is transferred to the creator and/or owner for a release oftransmission and/or sharing. It would also be conceivable that thesocial media platform or the chat platform applies a restriction ofallowed digital media files only for those which are digital media filesidentifiable under copyright laws. As a result, advantageously adistribution of digital media files with illegal contents can beprevented and/or can be investigated more easily by the police (forexample by a court order to disclose the true user identity).Furthermore, in particular a licensing or sale of rights to a digitalmedia file also constitutes usage. It is further conceivable that atransfer of rights to a digital media file is registered in theblockchain or in the Distributed Ledger in the context of the digitalmedia file.

Furthermore, a recording apparatus having a computer functionality isproposed, with the application software that is at least configured forexecuting the method for assigning a creator to a digital media file. Inparticular, the recording apparatus having the computer functionality isrealized as a digital camera, as a smartphone with a digital camera oras a personal computer with a digital camera, for example a tablet. Thisin particular enables advantageous creator identification.

In addition, a display device having a computer functionality isproposed, with an application software that is at least configured forexecuting the method for a distribution of digital media files. Inparticular, the display device having the computer functionality isrealized as a smartphone with a screen or as a personal computer with ascreen. It is conceivable that in the decentral distribution a directconnection is established between the display device and the recordingapparatus. Advantageously, legal distribution and/or licensing ofdigital media files and/or legal sale of rights to digital media filesis enabled without an intermediary instance, like for example an imageagency, preferably directly from a creator to an end user. Thisadvantageously allows dispensing with computing capacities, costs and/ortime delays caused by the intermediary instance.

The method according to the invention, the recording apparatus accordingto the invention and the display device according to the invention shallherein not be limited to the application and implementation describedabove. In particular, in order to fulfill a functionality describedhere, the method according to the invention, the recording apparatusaccording to the invention and the display device according to theinvention may comprise a number of individual elements, components andunits that differs from a number given here.
